80C154/83C154

This diagram indicates when signals are clocked internally. The time it takes the signals to propagate to the pins,

however, ranges from 25 to 125 ns. This propagation delay is dependent on variables such as temperature and pin

loading. Propagation also varies from output to output and component. Typically though (TA = 25Â°C fully loaded) RD

and WR propagation delays are approximately 50 ns. The other signals are typically 85 ns. Propagation delays are

incorporated in the AC specifications.
